From Wikipedia, the free encyclopedia
First launched in 1953, the American Redstone rocket (Redstone missile) was a direct descendant of the German V-2. Redstone was used for the first live nuclear missile tests by the United States. It was also referred to as the Redstone MRBM (medium range ballistic missile), although in the true sense of the definition within the United States Department of Defense of MRBM: a missile with a maximum range between 1,000 km and 3,000 km, this was a misnomer.

The Redstone missile was in active service with The US Army from June 1958 to June 1964. Some Redstone missiles were modified in the mid to late 1960's for follow-on special test projects. For one such project the missiles were called Sparta rockets.
For its role as a US Army field artillery theatre ballistic missile, Redstone earned the accolade of being "the Army's Workhorse". For its roles in non-military applications, Redstone deservedly earned the nickname "Old Reliable".
